光滑的tiledmap渲染说明

Question

Im trying to render a map for a game I am making using tiled map from the slick class but im having a lot of trouble understanding the difference between the parameters x and y. Below is a googled explanation but im not understanding it

public void render(int x,
               int y,
               int sx,
               int sy,
               int width,
               int height)
Render a section of the tile map
Parameters:
x - The x location to render at
y - The y location to render at
sx - The x tile location to start rendering
sy - The y tile location to start rendering
width - The width of the section to render (in tiles)
height - The height of the secton to render (in tiles)

My game consists of a car and a camera locked onto it which will follow the car around on the map. The map starts to render as the car move. Could someone give me an explanation on how x and y and sx and sy applies to this.

Answer 1

The render function takes a rectangular area of tiles and draws them onto a rectangular area of pixels on the screen.

• x and y specify the top left corner of the pixel rectangle

• sx and sy specify the top left corner of the tile rectangle

• width and height specify the area of the tile rectangle
